PLOW.

Application filed March 14, 1927.

My invention relates to plows, and more particularly to means wherein the depth of the furrow may be regulated by adjustment of the plow beam.

In the accompanying drawings- F igure 1 is a side view of a plow showing the mounting of the plow beam;

Figure 2 is a section on line 2-2`, Figure 1.

The plow consists. of amold board mounted in the ordinary way to a landside 1, which is provided with a plowshare 3. The landside 1 is continued upwards and is provided with a reccss 5 in which the plow beam 4 may be mounted. This beam 11 is pivoted at 6 by means of a bolt and is provided rearwardly of said bolt with cross openings in the form of ares, into which bolts 7 and 8 are mounted.

By referring to Figure 2, wherein bolt 8 is shown, it will be seen that the same passes through the recess in the landside and is tghtened thereon by means of a nut. By this means, if the screws 7 and 8 are loosened the beam may be rocked vertically so as to clip or raise the plowshare, and when the proper adjustment is obtained, the nuts on bolts 7 and 8 are tightened to fasten the plow beamv 4 in position on the plow and prevent a side play.

In order to support the plow beam vertically in the landside, the lower wall of the depression is provided with steps 13, 14:, and 15, on which a wedge or block 12 may rest. As shown in Figure 1, the block 12 rests on step 13 and the plow beam is adjusted to bear on the top of said block. So as to t-ightly press the plow beam on the block 12, a set screw 10 is mounted in the upper wall of the depression in the landside and When tightened over the plow beam 4 will prevent any play between block 12 and the screw 10. This fastening, together with the bolts 7 and 8 will ofl`er a secure adjustment of the plow beam in any position required to regulate the depth of the furro'vv.

The mount-ing of the set screw 10 in the upper wall of the depression in the landside is effected by a threaded perforation in a lug 9, made thicker than the wall of the depression to give more purchase to the sc-rew. The

Serial No. 175,095.

set screw may be fastened in any adjusted position by a set nut 11.

It will readily bc noted that a construction such as previously described ofi'ers many advantages over the construction of adjustable beams heretofore in use. By making the landside continuous and mounting;`` the beam directly on the same, a very rigid connection is provided.

I have illustrated one means of carrying my invention into practice but it will be understood that many changes may be made without departing from the spirit of the invent-ion as covercd by the following claims:

1. In a plow of the class described, a. landside, a depression at the upper part thereof, a plow beam pivotally mounted in said depression, a series of steps in the lower wall of said depression, a block formed to rest on any of said steps so as to support the plow beam, and means to tighten said block on said steps.

2. In'a plow of the Character described, a landside, a beam pivotally supported thereon, means to adjust said beam to determine the depth of the furrow, comprising stepsin the landside positioned adjaccnt the rear end of said plow beam, a block formed to rest on any of said steps, and a set screw mounted in said landside above said beam positioned to tighten said beam against said block.

3. In a plow of the class described, a landside extending up to the top ,of said plow, a depression 'at the upper end, a plowv beam pivotally mounted in said depression, an integral extension in said plow beam back of said pivot, cross notches in said extension, bolts mounted in said notches and through said depression to maintain said plowbeam against the wall of said depression, a series of steps in vthe lower wall of said depressions, a block formed to rest on said steps, a set screw mounted in the upper wall of said depressions over said plow beam positioned to tighten said plow beam against said block, and means to lock said setscrew.

In testimony of the foregoing, I have hereto affiXed my signature.

CHARLES A. LOUIS MONSARRAT.
